The Societies' Building housed the founder engineering societies, an auditorium and a joint library, while the Club offered social and residential space. Their matching base-shaft-capital facades and surviving interiors support their architectural and historical value.","narrative":"Two linked buildings on the blocks between West 39th and West 40th Streets in Midtown Manhattan form this complex, built in 1905-07 for the engineering profession. The Engineering Societies' Building on West 39th Street, by Hale & Morse, held an auditorium, society offices and a shared library. The Engineers' Club on West 40th Street, by Whitfield & King, offered clubrooms, a banquet hall and 66 bedrooms. Andrew Carnegie's main thought was a structure in two parts, similar in exterior treatment yet separate in interior arrangement. Both facades follow the base-shaft-capital pattern, with rusticated bases, double-height arcades and arcaded tops. The Societies' Building is limestone, brick and terra cotta; the Club is marble and red brick. Later changes include a 1913 addition on West 39th Street and two stories added in 1916. Today the Club's rooms are apartments, though carved woodwork, fireplaces and a grand staircase survive. The complex includes three contributing buildings and one non-contributing building.","period_of_significance":null,"architect_builder":"Hale & Morse (Engineering Societies' Building); Whitfield & King (Engineers' Club); Beverly S.
